Most course creators pick a platform, upload their videos, and assume the checkout will work at any scale. Then they run a launch, hit a transaction threshold buried in the fine print, and watch sales freeze until the next billing cycle.
These limits aren’t about storage or bandwidth—they’re about how many individual purchases your platform will process in a calendar month. Cross the line and you’re either locked out, auto-upgraded to a higher tier, or hit with overage fees that can double your hosting cost overnight.
Where the walls are
Teachable’s Basic plan ($59/month) caps you at 250 transactions per month. That’s total checkouts: course sales, upsells, payment-plan installments. If you sell a $97 course and 260 people buy it in October, the last ten get an error page unless you’re already on the Pro plan ($159/month), which raises the ceiling to 2,000 transactions.
Thinkific’s Basic plan ($49/month) has no stated transaction cap, but it restricts you to one published course and one admin user. You hit scaling friction through feature gates, not checkout limits. The Start plan ($99/month) lifts most restrictions but still charges a $0.10 fee per enrollment if you use Thinkific Payments instead of connecting Stripe directly.
Podia bundles email, courses, and digital downloads under one roof. Its Mover plan ($39/month) has no transaction cap and no platform fees—but you’re limited to one site and basic email automation. The Shaker plan ($89/month) adds affiliates, code editors, and advanced workflows, still with no transaction ceiling.
Kajabi doesn’t publish a transaction limit, but its entry-tier pricing starts at $149/month for up to 10,000 contacts and 1,000 active members. You’re more likely to hit a contact-list cap than a sales cap, but both can shut down growth mid-funnel.
What actually breaks
Transaction limits don’t just stop new sales—they cascade. If you’re running a payment plan (three installments over 90 days), each installment counts as a separate transaction. A single buyer on a payment plan consumes three transaction slots, even though you only made one sale.
Upsells and order bumps multiply the count too. Sell a course with a one-click upsell for templates, and that’s two transactions per buyer. Run a launch weekend with 200 buyers, half of whom take the upsell, and you’ve burned 300 transactions in 72 hours.
Affiliate payouts don’t count toward transaction limits, but refunds do. Issue a refund in Teachable and it doesn’t refund your transaction count—you’ve still used the slot. If you’re near your cap and process ten refunds, those ten slots are gone until next month.
How to plan around it
Before you launch, calculate your expected transaction load. Multiply projected buyers by the number of transaction events per buyer: initial purchase, upsells, and any payment-plan installments. Add 20% margin for refunds and edge cases.
If your platform caps transactions, map your pricing tier against your funnel. Teachable’s Pro plan at $159/month makes sense if you expect 500–2,000 transactions per month. Below that, you’re overpaying. Above that, you need the next tier or a migration plan.
For payment plans, front-load as much revenue as possible. Offer a small discount for paying in full, or structure plans as two installments instead of three. Fewer installments mean fewer transaction events and more predictable capacity.
Connect Stripe or PayPal directly when the platform allows it. Thinkific, Podia, and Teachable all support direct payment gateways, which often bypass per-transaction fees and give you more control over dispute handling and payout timing.
When to switch platforms
If you’re consistently hitting transaction caps, moving to a platform with no ceiling—or migrating to a self-hosted solution like WooCommerce or MemberPress—becomes cheaper than upgrading tiers every quarter.
Self-hosting adds operational overhead: you’re responsible for uptime, PCI compliance (handled by Stripe, but you still configure it), and plugin updates. But you eliminate per-transaction fees and artificial caps. A $30/month WordPress host plus a $199/year membership plugin can handle 10,000 transactions a month without flinching.
Before you migrate, export everything: customer lists, transaction history, course content, email sequences. Most platforms let you export CSVs and download video files, but automation rules and custom CSS don’t transfer cleanly. Budget two weeks for a clean migration, longer if you have complex funnels.
If you’re planning a launch in the next 60 days, check your transaction cap today. Open your billing page, find the limit, and multiply your projected sales by the number of transaction events per buyer. If the math puts you within 20% of the cap, upgrade now—or risk going dark the day your launch peaks.
